While both the HTL QT Desktop Laser Engraver and the CO2 Laser Engraver have a compact design, the size of the laser engraver depends on the projects that you will be working on. You will need an engraver that will easily fit in your office space or workshop but will be large enough to handle the projects that you will be working on. If you are working on extremely large projects, you may want to use a professional service. http://www.stonecnc.net/stone-diamond-tools/engraving-tools/
